LDA

Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec

this file contain matlab code for noise in communication.

It is the Simulated Annealing method coded by matlab and has a good results.

function Colored(flag, corr) Kalman filter simulation with colored (time correlated) measurement noise. INPUTS: flag = 0 means ignore the time correlation of the measurement noise 1 means augment the system state 2 means use the Bryson/Henrikson approach corr = magnitude of measurement noise correlation <= 1

在需要检测的音频中加入白噪声序列来检测音频的特性(Add white noise sequence to be detected in the audio features to detect audio)

量化程序，采用标准的Loyd-Max algorithm，提供了一个实例，并对结果进行了分析。很有学习的价值。(Quantification procedures, the use of standard Loyd-Max algorithm, provides an example of the results are analyzed. Great learning value.)

我写的一个小程序。用MATLAB自动生成任意维数和任意数量的数据，并且根据这些数据用一定的方法统计出这些点的概率密度。(I wrote a small program. MATLAB automatically generated using an arbitrary dimension and arbitrary amount of data, and based on these data in a certain way to the statistics of the probability density of these points.)

说明：  对一个50个结点（更多的节点的网络只需要修改模块中的标量维数就行）的复杂非线性耦合网络进行同步化仿真。首先生成K矩阵，然后运行simulink，即可得到50个洛仑兹混沌节点复杂网络的同步化曲线。(Of a 50-node (more network nodes only need to modify module scalar dimension on the line) the complexity of nonlinear coupling network synchronization simulation. First Generation K matrix, and then run the simulink, can be chaotic 50 Lorentz complex network node synchronization curve.)

Matlab编写的SPIHT 也叫层树分集压缩算法 本算法目前适合处理8*8的矩阵 <由于时间关系 本算法还不能对大的图像进行操作 但是主要的思想算法都在 只要稍做修改即可>希望对大家会有帮助 (Matlab prepared SPIHT also called tree diversity layer compression algorithm suitable for the processing algorithm currently 8* 8 the Matrix)
